I have a shell script that builds a bunch of source archives one
after another. Here's an excerpt:

echo Installing Sh-utils-2.0
tar -xzvf sh-utils-2.0.tar.gz
cd sh-utils-2.0
patch -Np1 -i ../sh-utils-2.0.patch
LDFLAGS="-static" ./configure --prefix=$LFS/static \
--disable-nls
make
make install
cd ..
rm -rf sh-utils-2.0/

echo Installing Tar-1.13
tar -xzvf tar-1.13.tar.gz
cd tar-1.13
patch -Np1 -i ../tar-1.13.patch
LDFLAGS="-static" ./configure --prefix=$LFS/static --disable-nls
make
make install
cd ..
rm -rf tar-1.13/

How do I trap errors from make, patch, etc., and exit the script
if there is an error?

TIA

assuming yer running your script in a bash shell, (probably true),
you can use stuff like:

make install || ( echo "ERROR: $? make install" && exit 1 )

if you want to use lots of errortesting, it's handy to a have:

function errorexit () {
echo ERROR: $*
exit 1
}

then, yer script can simply say:

make install || errorexit $? make install

Thanks much. That's what I was looking for.
